Embodiment Construction

[0032] The present application will be described in detail through three examples below. The specific examples are only for clearly explaining various details of the technical solution in the application, and they do not limit the protection scope of the technical solution in the application. Those skilled in the art may reasonably make changes or additions or subtractions to the technical features in each embodiment according to actual conditions within the scope of understanding of those skilled in the art.

[0033] With the development of electric vehicles, the driving mode of electric vehicles is also changing. Compared with the fuel engine, the structure of the motor is simple, and the installation and maintenance are more convenient. The compactness of the motor makes it an option to combine the wheels with the motor to provide power for the car. This application is an invention created under such circumstances. It should be noted that the motor integrated with the whee...

Abstract

The invention provides a wide-base wheel. The wide-base wheel specifically comprises a main rim and an outer rim, the edge of the inner side end face of the axial outer diameter face of the main rim is provided with an extending first bevel edge, the outer rim is arranged on a first step on the outer diameter face of the main rim in a sleeving mode from one side of the outer side end face of the main rim, and the outer diameter face of the outer rim is provided with an extending second bevel edge. The outer rim is connected with an annular flange on the axial outer side end face of the main rim through a flange arranged on the inner diameter face of the outer rim and a connecting structure, and a tire bead seat used for installing a tire is formed between the first bevel edge and the second bevel edge. The inner diameter face of the main rim forms an inner cavity of the wheel, and the inner cavity serves as a space for installing a hub motor. The inner cavity of the wheel occupies themain position of the axial size of the wheel, and the middle of the wheel is not separated by other structures, so that a large-size high-power hub motor can be arranged in the inner cavity of the wheel through the structure. The invention further discloses a wide-base wheel assembly and an electric vehicle.

Description

technical field [0001] The present application relates to a wheel, in particular to a wide-based wheel that can be loaded with an in-wheel motor. The present application also relates to a wide-based wheel assembly using the wide-based wheel and an electric vehicle using the wide-based wheel. Background technique [0002] In recent years, new energy vehicles have developed rapidly, especially new energy electric vehicles. Traditional new energy electric vehicles rely on the on-board power system to transmit power through the transmission shaft. Traditional mechanical transmission systems such as couplings and transmission shafts have complex structures. It is bulky, takes up design space, and has low transmission efficiency; in order to solve the above problems and combine the characteristics of electric vehicles, the in-wheel electric drive system was born in response to the situation. The hub motor drive system installs the drive motor in the inner cavity of the wheel, so t...
